| Baby Sharks: Small Subgroup Attacks on DKG Implementations | Omer Shlomovits | 26m |
Claims that common DKG code skips subgroup sanitization and so allows concrete attacks on implementations using Curve25519 and BLS12-381. Uses analysis of… | ||
| Verifiable Luck | Jeffrey Burdges | 35m |
Defines verifiable random functions as a PRF glued to a signature and stresses the danger of leaking the pre-output (developers misuse it); gives concrete… | ||
| Asynchronous Distributed Key Generation | Eleftherios Kokoris-Kogias | 27m |
Event: Workshop on Real-World Decentralized Cryptography
Full Presentation Title: Asynchronous Distributed Key Generation for Computational Secure Randomness… | ||
| Aggregatable Distributed Key Generation | Mary Maller | 31m |
New DKG construction is publicly verifiable, uses encrypted secret-share outputs plus non-interactive proofs so there are no complaint rounds, and it… | ||
| Towards Scalable Threshold Cryptosystems | Alin Tomescu | 33m |
Provides concrete algorithms and measurements: uses KZG commitments plus a polynomial multi-point evaluation to build an authenticated multi-point evaluation… | ||
| Decentralized Cryptography: A Distant Dream or an Immediate Possibility? | Ittai Ibrahim, Andrew Miller, Christian Cachin, Harry Halpin, Aniket Kate | 01h 14m |
Panel argues threshold crypto moves from theory to scattered practice: live trusted setup ceremonies with dozens of participants produce SNARK parameters, but… | ||
| Validity and the future of blockchains | Dankrad Feist | 24m |
Classifies execution approaches for sharding: committee attestation versus data-availability via erasure coding (Reed–Solomon style) with random sampling, 200×… | ||
